According to the RSS satellite data, whose value for April 2014 is just in, the global warming trend in the 17 years 9 months since August 1996 is zero. The 212 months without global warming represents more than half the 423-month satellite data record, which began in January 1979. No one now in high school has lived through global warming.

The long Pause may well come to an end by this winter, when an el Niño event is expected in the equatorial eastern Pacific, causing global temperature to rise quite sharply. The el Niños of 1998, 2007, and 2010 are visible in the graph. El Niños occur about every three or four years, though no one is entirely sure what triggers them. They cause a temporary spike in temperature, often followed by a sharp drop during the la Niña phase, as can be seen in 1999, 2008, and 2011-2012, where there was a “double-dip” la Niña.

The ratio of el Niños to la Niñas tends to fall during the 30-year negative or cooling phases of the Pacific Decadal Oscillation, the latest of which began in late 2001. So, though the Pause may pause for a few months at the turn of the year, it may well resume late in 2015.

Either way, it is ever clearer that global warming has not been happening at anything like the rate predicted by the climate models, and is not at all likely to occur even at the much-reduced rate now predicted. There could be as little as 1 Cº global warming this century, not the 3-4 Cº predicted by the IPCC.
